I’ve just completed all 3 series. Bloody loved it! But I feel like the story about Boris/Alexander was never resolved. We know he came to our original world in 1986 having murdered someone. But we don’t know who or why or when? And then the detective seemed to be onto him. But where did that detective come from? And was I right in thinking he was the really old guy from the past.... the father of the blind boy? Is that the connection with Boris?!
Or have I missed something?
